EXPANSION-JOINT.

To all it mayconcem Y v I Be it known that I, EDWARD TYLER, a c1t1zen ofthe United States, and a resident of Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Expansion Joints, of which the following is a .full,

- clear, and exact description, reference being hadto the accompanyingdrawings, forming {part of this specification, in which j Figure 1 is aview partly inside elevation and partly in vertical'section showing. oneterm of expansion joint embodying my invention; Fig. 2 is a plan view ofthe same;

The other conduit section is similarlybolted to an end ring 9" supported in a second cradle. The

Theadvantages of my inventlon'will be apparent since it provides anexpansion joint of very. simple and efliclent character capable of usewith pipes of large diameters and where relatively large expansion andcontraction movements must be taken care of. The expansion joint can bereadily at one end to said end member, an opposite end member to whichthe other end of. the
